I would have hoped the 1.0 ISO could already be made correct. Older ISOs work on cooperative motherboards as well though, it appears only old Macs are affected. A more recent 2014 Macbook Air boots fine though. As for the latter, here are my findings when booting the USB installer: | | Nvidia PC with | AMD GPU PC with = | | | Asus P8H67-V board | Asus P8H67-? = | |---------------------+-----------------------+--------------------------= ------------| | x86_64 | boots with UEFI | boots but graphical insta= ller | | unpatched master | and legacy | only works with UEFI = | |---------------------+-----------------------+--------------------------= ------------| | x86_64 with Danny's | boots with UEFI | boots but graphical insta= ller | | patches (wip6) | and legacy | only works with UEFI = | |---------------------+-----------------------+--------------------------= ------------| | i686 | boots graphical | boots in legacy mode w/o = | | unpatched master | installer in legacy | graphical installer, boot= s from | | | mode, boots from | harddisk instead when sel= ecting UEFI | | | harddisk instead when | = | | | selecting UEFI | = | |---------------------+-----------------------+--------------------------= ------------| | i686 with Danny's | boots graphical | boots in legacy mode w/o = | | patches (wip6) | installer in legacy | graphical installer, boot= s from | | | mode, boots from | harddisk instead when sel= ecting UEFI | | | harddisk instead when | = | | | selecting UEFI | = | |---------------------+-----------------------+--------------------------= ------------| | | 2010 Macbook | Lenovo Ideapad 100S | |---------------------+--------------------+---------------------| | x86_64 | boot gets stuck | does not appear | | unpatched master | before listing | in the boot | | | devices to boot | selection | | | from | | |---------------------+--------------------+---------------------| | x86_64 with Danny's | boots fine with a | does not appear | | patches (wip6) | selection of =E2=80=9CEFI | in the boot = | | | Boot=E2=80=9D and =E2=80=9CGRUB | selection = | | | 2.02=E2=80=9D; both appear | = | | | to boot in UEFI | | | | mode though | | |---------------------+--------------------+---------------------| | i686 | boot gets stuck | boots fine (is | | unpatched master | before listing | only shown as EFI | | | devices to boot | device) | | | from | | |---------------------+--------------------+---------------------| | i686 with Danny's | only =E2=80=9CGRUB 2.02=E2=80=9D | boots fine (= is | | patches (wip6) | can be selected, | only shown as EFI | | | but boots from | device) | | | harddisk instead | | |---------------------+--------------------+---------------------| I wonder why guixsd-install-0.15.0.i686-linux.iso did not boot on the Lenovo Ideapad 100S before. Windows claims the Lenovo is a 32-bit machine only btw. Regards, Florian
